2. Description of the Related Art FIG. 2 is a longitudinal cross-sectional view showing a conventional disk cleaning device disclosed in, for example, Japanese Patent Application Laid-Open No. 64-46278. In the figure, information data is recorded in a cartridge (1). A disk (2) is stored. (7) is a spindle with a gear (7a) machined at the tip and a gear (7b) formed in the middle part, with a handle (6) attached to the top and a spline shaft at the bottom. . (8a) and (8b) are reduction gears, which are the gear (7b) of the spindle (7) and the gear (7b) of the spindle (7).
) The gear part (9a) of the chuck (9) rotates around the axis
They mesh well with each other. (5) is a housing, (10) is a cam with a wave-shaped outer periphery, and the center meshes with the spline shaft of the spindle (7). (4) is a table that fits into the shutter opening of the cartridge (1) to enable centering of the disk (2) and chuck (9). (3) is a cleaning tool made of a cylindrical brush or cloth; (11) is an interlocking pin that contacts the outer peripheral surface of the cam (10) and swings the cleaning tool (3) from side to side;
2) is a spring that keeps the interlocking pin (11) in constant contact with the cam (10).

Next, the operation will be explained. Table (4
) onto the cartridge (1) with the shutter of the cartridge (1) open. At this time, clean the cleaning tools (3
) and the disk (2) come into contact with each other. Next, the housing (5) is lowered from above the cartridge (1) and the spline shaft portion of the spindle (7) is attached to the disk (2).
) through the center hole of the spindle (7), and insert the gear part (7a) at the tip of the spindle (7) into the cam (10
) onto the cartridge (1) while engaging with the center part of the cartridge (1). At this time, the tip of the chuck (9) is fitted into the center hole of the disk (2) while giving rotation to the disk (2).

In the above state, when the handle (6) is rotated, the cam (10) rotates in synchronization with the rotation, and the interlocking pin (11) that is in contact with the cam (10) ) moves along the outer periphery of the As a result, the interlocking pin (1
The cleaning tool (3), which is integrated with 1), reciprocates in the lateral direction. On the other hand, the disk (2) is rotated by the chuck (9) via the reduction gear (8) at a slower rate than the rotation of the cam (10) described above. The disk (2) is cleaned by the above operations.

[Problems to be Solved by the Invention] Since the conventional disc cleaning device is constructed as described above, the cartridge must be reversed in order to clean both sides of the disc. There are problems in that it is time consuming and cleaning tools tend to get dirty due to frequent cleaning.

The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a disk cleaning device that can reduce the time for cleaning both sides of a disk by half, and also reduce the degree of contamination of the cleaning tool by half. With the goal.

[0007]

[Means for Solving the Problems] A disk cleaning device according to the present invention has cleaning tools arranged so as to come into contact with both surfaces of a disk.

[0008]

[Operation] The cleaning mechanism according to the present invention cleans both sides of the disk simultaneously during the cleaning operation by arranging the cleaning tool so as to contact both sides of the disk.

[0009]

Embodiment FIG. 1 shows an embodiment of the present invention, in which (2) is a disk for recording information data;
is a cartridge containing a disk (2), and (7) has a gear (7a) machined at the tip, and a gear (7a) in the middle part.
7b), the upper part of which is attached with a handle (6), and the lower part of which is a spline shaft. (8a) and (8b) are reduction gears, and the gear part (7b) of the spindle (7) and the spindle (7)
They mesh with the gear portion (9a) of the chuck (9), which rotates around the axis.

Reference numeral (4) denotes a table for positioning the cartridge (1), and a cam (10) whose outer periphery is shaped like a wave tooth is provided inside the table. (5) is a housing, inside of which are reduction gears (8a), (8b), a cam (15) whose outer periphery is in the shape of a wave tooth and whose upper part is a gear (15a), and this cam (15). Gear part (15a
) is provided with a speed increasing gear (13) that meshes with the gear. (14
) is a bearing that allows the cam (15) to rotate around the chuck (9).

(11a) and (11b) are interlocking pins, cleaning tools (3a) and (3b) are attached to the centers of the interlocking pins (11a) and (11b), respectively, and springs (12a)
), (12b), the interlocking pins (11a), (11
b) are in contact with the cams (10) and (15), respectively. The cleaning tools (3a) (3b) are composed of cylindrical brushes or cloth.

Next, the operation will be explained. Table (4
) When the cartridge (1) is inserted into the cartridge (1) with the shutter of the cartridge (1) opened, the cleaning tool (3a) and the lower surface of the disk (2) come into contact with each other. Next, the housing (5) is lowered from above the fitted cartridge (1), and the spline shaft portion of the spindle (7) is attached to the disc (2).
) through the center hole of the spindle (7), and insert the gear part (7a) at the tip of the spindle (7) into the cam (10
Fit onto the cartridge (1) while engaging with the center part of a). At this time, the tip of the chuck (9) is fitted into the center hole of the disk (2) while giving rotation to the disk (2).

In the above state, when the handle (6) is rotated, the cam (10) rotates in synchronization with the rotation, and the interlocking pin (11a) that is in contact with the cam (10) ), the interlocking pin (11
The cleaning tool (3a) integrated with a) reciprocates laterally. Also, the rotation of the handle (6) is controlled by the spindle (
7) gear part (7b), reduction gear (8a), speed increase gear (
13) to the cam (15). Cam (15
) moves along the outer periphery of the cam (15), so that the cleaning tool (3b) integrated with the interlocking pin (11b) reciprocates in the lateral direction. On the other hand, the disk (2) is rotated by the chuck (9) via the reduction gear (8b) at a speed slower than the rotation of the aforementioned cams (10) and (15). With this kind of action,
Both sides of the disc (2) are cleaned at the same time.

[0014]

As described above, according to the present invention, since both sides of the disk can be cleaned at the same time, the cleaning time for both sides of the disk can be shortened, and the degree of dirt on the cleaning tool can be halved. There is.
